President Donald Trump signed into law the “One Big Beautiful Bill” on July 4. The bill included several agricultural aspects, such as the extension of the Clean Fuel Production Credit (45Z) through 2029. The credit supports the production of low-emission transportation fuels, such as ethanol, biodiesel, renewable diesel, and sustainable aviation fuel.

Originally created by the Inflation Reduction Act in 2022, the provision prevents the credit from being used for fuels produced by feedstock sources outside of North America. The changes support agricultural feedstocks, including corn and soybeans, while reducing the nation’s reliance on fossil fuels.
